SPECIFICATION			       	LEVEL/PATCH
Fast-Setting, Cement-Based Patching Compound

**************************************************************************************
DESCRIPTION: A fast setting, polymer-modified, cement based patching compound which, when mixed only with water, is used to patch fully cured concrete and exterior grade plywood prior to the installation of ceramic tile or dimension stone.  Ceramic tile or dimension stone can typically be installed in just 2 hours after application of the LEVEL/PATCH.

Specify for interior use only.

Specify for patching and filling cracks, holes, voids and depressions in concrete and exterior grade plywood subfloors (interior drywood only) prior to the installation of ceramic tiles, slate, marble, granite, and stone veneer floors.

Specify for repairing subfloors from 3/16” (5mm) to 1/2” (12mm) thickness.

Specify where a compatible bond with all ceramic tile adhesives, dry-set mortars, epoxies and polyurethane adhesives when these materials are subsequently used for the installation of ceramic tile or dimension stone.

DO NOT specify directly over gypsum floor patching compounds or lightweight concrete.

DO NOT specify for use as a concrete resurfacing material when concrete surface is to be left exposed or unprotected.

DO NOT specify in thickness above 1/2” (12mm).  Specify MAPECEM Premix Fast Setting One Component Polymer Modified Hydraulic Cement-Based Premixed Mortar.

DO NOT specify for leveling large surfaces. Specify ULTRA/PLAN or ULTRA/PLAN MB self-leveling underlayments (see data sheets for details).

DO NOT specify for use over particleboard, masonite, chipboard, Lauan, gypsum floor patching compounds, metal or similar dimensionally unstable substrates.

When specifying LEVEL/PATCH in the Cement-Based Patching Compound Section selected, add the appropriate articles or paragraphs under the applicable PART as indicated.

PART 3 EXECUTION

**************************************************************************************
Specifications for surface conditions are listed in the beginning of the specification of MAPEI’s Architectural Binder.  These specifications should be called out with the related work sections.  Delete non-applicable conditions.  (Refer to ANSI EXPLANATION AND NOTES section: AN-3 RELATED WORK SPECIFIED IN OTHER SECTIONS.)
**************************************************************************************

INSPECTION

Verify substrate surface is ready to receive work of this section.  Do not proceed with work until surfaces and conditions comply with manufacturer’s requirements.

INSTALLATION

Install cement based fast-setting patching compound in accordance with manufacturer’s printed instructions.

Install expansion and control joints in accordance with TCA method EJ171.

PROTECTION

Provide dry heat storage on site and deliver material at least 24 hours before use.

Protect from traffic, dirt or dust from other trades until final installation of floor covering.

Do not apply any adhesive or mortar material before LEVEL/PATCH is completely dry.

Protect from excessive heat and drafty conditions while curing

LEVEL/PATCH must be covered over with ceramic tile or dimension stone material.

**************************************************************************************
When dealing with cement-based products, it should be noted that temperature and humidity during and after installation of tile affect final curing time, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
